Do not group braille characters
In non-grouped mode, each letter is printed as is. this is the default if we are dealing with a symbol and not in bidirectional text mode. When we are in bidirectional text mode, for some reason, konsole treated a sequence of braile characters as "something that could be grouped into a single string", passed directly to the painter->drawText, producing strange results.
To test: paste a string of braile characters on the terminal, and change the profile (in advanced) from and to "bidirectional text rendering"
braile characters for testing: ⢸⣿⣿⡀⢰⢰ ⢀
You will see that the pixmap of them will change when we are in bidirectional mode.
